How to schedule and publish social posts made in Codex

1. Save the finished files for review

Have Codex finish and inspect the images first. Our skincare carousel used five 1080 × 1350 JPEGs. We saved them in slide order with the full caption.

Save these finished images and the caption as a private review Post in [workspace]. Confirm the slide count and order, and open the Post in the browser beside this chat. Do not schedule or publish it yet.

ReelGenie accepts 1–20 PNG, JPEG or WebP images, up to 8 MB per image and 12 MB for the Post. For TikTok photo delivery, use JPEG or WebP with a short side no larger than 1080 pixels and a long side no larger than 1920 pixels. A 1080 × 1350 portrait image fits those limits.

If you already have finished images, you can import them in ReelGenie instead. Codex needs the ReelGenie connection to save the files for you.

2. Review the saved Post

Open the post-details page and look for Ready for review. Check each slide, the complete caption and the workspace label. Make sure the images you are looking at are the revised files you want to send.

For Doola AU, we checked all five slides and the caption before approval. The Post stayed private while those checks happened.

If a caption needs changing, edit it and read it again. If the artwork is wrong, correct it in Codex and replace the affected image while the Post is still an unapproved draft. ReelGenie stores finished images; it does not edit the text inside them.

3. Choose the account and delivery mode

Ask Codex to list the connected accounts for the selected workspace. Check the handle and whether the account supports direct publication or an inbox draft.

Our Doola AU workspace had Instagram @pregnancy_doola and a TikTok Doola connection. The Instagram account could publish directly. TikTok photo delivery used the inbox workflow. The same approval therefore led to two different next steps.

List the connected accounts for this workspace. For each, tell me which formats and delivery modes are available. I want to send this Post to [exact account names]. Confirm them before approval.

Instagram supports eligible image and video delivery. For most accounts, TikTok photo delivery sends an inbox draft. YouTube requires a finished video; an image carousel is not a YouTube upload.

4. Publish now or set a date and timezone

In our chat, the user chose immediate delivery by saying, “approve and post them.” Codex confirmed the accounts and modes, then approved the reviewed versions.

To schedule instead, specify the date, time and timezone:

Schedule this reviewed Post for [date] at [time] in [timezone], to [exact account]. Read the saved schedule back to me. Do not send it immediately.

For example, “2 October 2026 at 9pm Australia/Sydney” is clearer than “tomorrow night.” Before confirming, check the date and destination in the approval dialog or Codex’s readback.

Codex needs publishing permission to execute an approval. If your connection does not have it, finish approval in ReelGenie. A TikTok schedule controls when the inbox draft is delivered; you still finish the public post in TikTok.

5. Read the result for each account

Doola AU’s Instagram delivery returned this published carousel. Its TikTok delivery returned an inbox draft. Lumo’s TikTok delivery in the same run also returned an inbox draft.

If Instagram succeeds and TikTok fails, check TikTok’s error before retrying. Keep the successful account out of the retry. For an unknown result, check what reached the account before sending again.

What counts toward the free allowance?

Free includes 30 posts a month per team, 1 brand and 3 connected accounts. One carousel sent to several destinations counts as one post; retries do not count again. Solo, Team and Agency include unlimited posts. See pricing for the plans.

For the creative steps before upload, follow our skincare-post tutorial. For different brands, use separate workspace briefs.
